T 'o all whom t may concern:

Be it known that we, Weinen Denison) and AnoUs'rUs R ll/io'rr, citizens of the United States ci .'Mnerice, residing at Detroit, in the county ot Wayne end State of Michigan, have invented certain new and useful Improvements in rilires, ofwhich the following is a speciiiceusioii,i reference being had therein to accompanying drawings.

This invention relates to tires, and perticularly to that type that depends upon solid elastic material for its resiliency, in contra distinction -to pneumatic Vtires depending upon air.

The primary object of our invention is to provide tire elements connected by an elastic element which tends to stretch when pressure is brought to beer upon the tire, and the tire elements are shaped and arranged to resist compression, yet contribute to a speedy action of the elestic element in cushioning e load supported by the tire.

A further 'object of our invention is to combine rubber and felt in e manner as to provide a durable, resilient tire that can be advantageously used in connection with bicycles, automobiles and various types oi' vehicles.

We attain the above and other objects by a combination and arrangement ofypnrts that will be hereinafter'specifically described end then claimed.

Reference will now be had to the drawing, wherein.a

Figure l is e cross sectional View' ot :i tire; Fig. 2 is e similar View of the tire when ressureis brought to bear upon the sonic; 4ig. 3 is e cross sectional view oit n modified .torni of tire, such as con be used in eonnection. with heevT vehicles, end liig. l is c similar -view o the 'tire when pressure is brought to bear upon the seme. i

lln describing our invention by eid of the views above referred to, we desire to point out that our invention is not limited to tbeprecise srrangement and shape of ports shown, e the above views ere merely illus tretive of an example whereby oniginvention may be applied inprectice. The Y1"ollowing description is thereforeto be broadly i construed es including substitute arrange ments and construction of. parts which nre the obvious equivalent ot those shown.

in the drawing, l. denotes side memoers or elements tbot ere segment slieped in cross flpeciiicotion or Letters battent.

section end prei'erablymede of felt', said' members being arranged whereby the flat ltstces thereof will form a groove l-shaped m cross section.

Arranged between the flat faces of the side members l is an intermediate member 2 that 1s sector-shaped in cross section `and mede of a material similar to the side members 1. The ilat feces of the intermediate member 2 confront the flat feces of the side membersll-4 and the confronting"l Het l:faces are meinteined in parallelism byzan elastic member or element 3 connecting said faces. The elastic member is preferablyrubber'of the best quality enclin, connecting' the members l and 2 seid members are impregnated with the rubberto e certain extent, whereb there iosa posltive connection between lsai mem# ers' member Q operates with the curved y of the 'side members 1 in forming e tire that is substanticllycircular in cross section, and seid members are incased by an outer tubo or casing 4 also of rubber which impregnotes the members it and 2 when vulcanized thereon. rll'be outer tube 4 'has athickened treed portion 5 ,reinforced by vcanvas 6 or a. suitable material. The thickened tread ortion. 5 forms e bese for the interme inte member 2 endwhen ressure or .e load is brought to beer upon t e tire, the same tends to flatten end the intermediate member2 Vto ride between tbe side members 1. The elsetic mernlfier` 3 is immediately brought into ection end by comparing the section lines of the elastic member (Fig. 2) with the section line of the same member (Fig. 1) itV will bev observed that the lines of force tend to stretch the gres-ter part of the elastic meinber while the .remaining port thereof is compressedB The intermediate member 2 has the action of en entering wedge that is not only retarded in its movement, but by reason of its 'connection with the side members, ellY 100 of said members sro immediately restored to Y their noi-mel position'rlon the*` pressure "or This tire comprises top and bottom mem# ifo',

bers 7 and 8, a main intermediate member, auxiliary intermediate members 10.I and an elastic member 1l. thetconnects itllllbf seidfV v members. The iletaceso the main inter` mediate meinbc'rl confront' the liet faces of 110 The curved surface oftheY intermediatc'ffb.,

the members 7, 8 and 10 and the flat faces of the members 7 and 8 confront the tlat faces of the members l0. YVith the elastic member connecting all of the Hat faces, there is a tendency for the main intermediate member 9 and the auxiliary intermediate members l0 to' separate when pressure or a load is brought to bear upon the tire; tbc lines of force being clearly shown in thesc two lignres;

. From the foregoing it will be observed that We have devised a simple, durable and inexpensive tire that can be manufactured Witl considerable facility, and wherein the cross sectionalshape of the various members permit of said members cooperating in resisting pressure, and that instead of the cushioning elements being compressed, as is common to a greatmany tires1 the action in connection With our improved tire is really that oi stretching. This is accomplished by arranging Aand shaping the various members whereby the elastic member will be stretched l instead of compressed.

1. vA tire comprising s ide members, an in-' termediate member having a Wedge action betweensaid side members, and an elastic f member connecting the confronting sides of said intermediate posed to form a groove, a sector-shaped intermediate. member arranged in the groove formed by said side members, an elastic member formed integral with thc confronting sides of said members, and a casing inclosing all of said members and having a thickened tread portion forming the base of said intermediate member.

In testimony whereof We aiiX our. signatures in presence of two witnesses.
